How to make Simplified Chinese preferences on Wikipedia stick

All you have to do is click the Edit button at the top of an article's page. In the page that you see afterward, you can make your changes and then save them.

You won't be able to edit some Wikipedia articles, however - instead of an Edit button, such protected articles will show a View Source button.

Also, when editing an article, it is recommended that you click Preview before you save your changes. This way, you can make sure that your changes were made as you intended.

For editing, you don't even have to log in. However, if you don't log in, there are a few disadvantages:

• Your IP address is posted and visible to the whole world - can lead to security issues
• You may lose some credibility

Before editing, I recommend you read some of Wikipedia's guidelines, so that you understand how Wikipedia works and how articles are supposed to be.

One last thing - it may be hard to get used to how formatting works on Wikipedia. That's why they wrote a cheatsheet for editors.

In an infobox such as the one in that article, you can refer to a image file like this: Image:Filename.jpg, but you have to first upload the image to either English Wikipedia itself or Wikimedia Commons. (Those are direct links to upload pages).

Commons is recommended (because then the image can be easily used in Wikipedias in other languages, and in other Wikimedia projects like Wiktionary), but the image needs to be freely licensed. As for English Wikipedia you are also allowed to upload non-free images under certain conditions (e.g. "fair use" rules). (Note that you are not allowed to just upload any random images off the internet, you need to either own the copyright or know that you have the right to use the image.)

Outside of an infobox, you'd typically refer to an image file like this:

[[Image:Example.jpg|right|thumb|Caption]]
